  奥巴马超卓演讲：我们为什么要上学

Hello, everybody! Thank you。 Thank you。 Thank you, everybody。 All right, everybody go ahead and have a seat。

   How is everybody doing today? (Applause。) How about Tim Spicer? (Applause。) I am here with students at Wakefield High School in Arlington, Virginia。

   And we’ve got students tuning in from all across America, from kindergarten through 12th grade。 And I am just so glad that all could join us today。

   And I want to thank Wakefield for being such an outstanding host。 Give yourselves a big round of applause。 (Applause。)。
